Description
Technical field
The present invention relates to a kind of weed killer herbicide, be specifically related to a kind of Botanical herbicide powder and preparation method thereof, belong to weed killer herbicide processing technique field.
Background technology
In the later stage forties 20th century, chemical synthetic pesticide gains great popularity because of the feature such as efficient, quick-acting, insecticidal spectrum is wide, and this makes the research of botanical pesticide and use once to be absorbed in low ebb.But along with the use of chemical pesticide, its drawback also reveals gradually, such as " 3R " problem (residual, pesticide resistance, insect rampant again).Botanical pesticide causes the concern of people again because of features such as it are efficient, low toxicity, low-residual, selectivity are high, pest not easily develops immunity to drugs, become the focus of current pesticide research.Because botanical pesticide is low to person poultry toxicity, easily degrade in the environment, essentially no obvious residual hazard problem.Therefore, botanical pesticide can be applied to the aspects such as vegetables, tealeaves, traditional Chinese medicine, the production of flowers and plants and urban afforestation prevention and elimination of disease and pests.
Nowadays, global agrochemical market continues to increase, and pesticide market sales volume is up to about 30,000,000,000 dollars, and year increases by 1.2%.Wherein weed killer herbicide is about 15,000,000,000 dollars, accounts for 50%, and year increases by 1.2%.Weed killer herbicide also known as weedicide, in order to eliminate or to suppress a class material of plant growth.Effect is by the impact of weed killer herbicide, plant and environmental condition Three factors.Be divided into by effect go out natural disposition and selective herbicide, conventional kind is organic compound.The noxious plants such as the ground weeds such as control farmland, orchard, floral nursery, grassland and uncultivated area, railway line, river course, reservoir, warehouse, assorted filling, assorted tree can be widely used in.Along with the development of Chinese agricultural modernization and the progressively transfer of agricultural workforce, cultivation tillage method trends towards scale and intensive, significantly increases the demand of agricultural chemicals.Wherein, weed killer herbicide growth rate in recent years, far above insecticide and bactericide development level, accounts for 1/3 of agricultural chemicals output proportion.Current national farmland chemical weed control area has reached about 0.53 hundred million hectare, adds more than 10 times compared with 1980.Although the development of weed killer herbicide is rapid, but still there is many problems.One is that herbicide resistance is on the rise.Over the past two decades, the different weeds polytype weed killer herbicide different to chemical constitution creates resistance to have at least the country of more than 30 to find in world wide; Two is that herbicide products on the market also exists the problems such as herbicide spectral limit is narrow, efficiency is low, safety shortcoming.
The thick thick bull pine of cusp scape; the irregular wrinkle striped of surface tool; distribution is all had in areas such as China Taiwan, Guangdong, Guangxi, Yunnan; research shows; the methanolic extract of cusp flower can suppress the growth of rice seedling; inhibitory action is because of the sampling point of cusp flower and leaf age and variant: the extract of reproductive organs is the strongest to rice inhibiting effect, and be secondly leaf, stem, the inhibitory action of root is the poorest; The cusp flower inhibitory action that leaf age is large is strong.Fragrant eupatorium herb ethanol extract has allelopathy in various degree to cowpea, green cucumber, radish, cabbage heart, Chinese cabbage, a variety of Chinese cabbage, paddy rice and barnyard grass.In addition, active ingredient weed growth being played to suppression is also rich in soapberry exosper.The present invention utilizes soapberry exosper extract, cusp flower extract, fragrant eupatorium herb extract to be that the exploitation of main herbicidal active component is a kind of efficient, environmentally friendly and not easily produce the weed killer herbicide pulvis of resistance, overcomes prior art Problems existing.
Summary of the invention
The object of this invention is to provide a kind of Botanical herbicide powder, this weed killer herbicide pulvis good water solubility, can be used alone or use with other mixture of herbicides, has efficient, environmentally friendly and not easily produces the advantages such as resistance.
